ISRAEL S. MEAD, OF BLUE EARTH CITY, MINNESOTA.

IMPROVEMENT IN WATER-HETERS.

Specification forming part of Letters Patent No. 142,035, dated August19, 1873; application tiled May 14, 1873.

To all whom 'it may concer-n:

Be it known that I, ISRAEL S. MEAD, of Blue Earth City, county ofFaribault, in the State of Minnesota, have invented certain Improvementsin Heaters for Water and other Liquids, of which the following is aspecification:

My invention relates to the production, as a new article of manufacture,of an annular heater, adapted to be readily applied to the exterior of astove-pipe, or to the drum of a stove, for the purpose of heating wateror other liquids for domestic or other purposes, and which will be foundparticularly useful in eases of illness, or at other times when it isvnot convenient to employ the ordinary cooking-stove, or when personshave not the use of such accommodations.

In carrying out my invention, I construct my heater ot' two plates ofmetal, iirmly soldered, riveted, or otherwise connected together, so asto form an annular space between such plates. The upper and lower endsof these annular plates or rings are then connected together by annularplates, the plate at the upper end being provided with an aperture,(covered by a slide or eap,) through which water to be heated issupplied to the apparatus. A second aperture is also formed in the upperplate, towhich a pipe or tube is connected, for the purpose of allowingsteam to esca-pe. This pipe or tube is conducted into the stove-pipe, orinto tle interior ot' the drum of the stove. A gage is formed on theside of the apparatus, connected with the lower portion or' the interiorof the heater, in order to indicate the quantity of water or otherliquid from time to time contained in the heater. A tap or faucet isprovided', by means of which the water or other liquid may be drawn fromthe heater.

But that my` invention may be fully understood, I will describe the samein detail by aid of the accompanying drawings.

Figure 1 represents a side view, partly in section, and Fig. 2 a plan,of my improved heater applied to a stove-pipe.

a represents a portion ot' a stOVepipe, and b my improved heaterappliedthereto. b1 b2 are two plates of metal, riveted or otherwiseconnected together, so as to leave an annular space, C, between them,the inner plate, b2, being formed into a ring of the desired size to itthe stove-pipe a., while the plate b1 may form a ring ot' any desiredsize, according to the desired capacity of the chamber or space C. Theupper and lower ends ot' the annular plates or rings b1 b2 are connectedtogether by means of annular plates d e. The plate d., at the upper end,is provided with an aperture, d1, (provided with a slide or cap, 612,)through which water or other liquid is supplied to the chamber G.Another aperture is formed in the plate d, at d3, to which a pipe ortube, d4, is connected, for the purpose ot'allowing steam to escapethereby into'the stove-pipe et. f is a glass gage, formed on the sideot' the appa ratus, and connected, at f', with the chamber C, in orderto indicate from time to time the quantity of water contained in suchchamber. gis a tap or faucet, through which water or other liquid may bedrawn from the apparatus, whenrequired. his a gallery, which rests onthe stove-plate, and may be employed to support the heater.

Fig. 3 represents one of my improved heaters applied to the exterior ofthe drum of a stove.

In this view the same letters of reference are employed to indicatecorresponding parts, so that further description is unnecessary.

It will be readily seen that heaters com structed according to myinvention may be readily applied to or removed from stove-pipes or thedrums of stoves without necessitating the alteration ot' any parts ot'the same, and, when not required, can be easily removed.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

As a new article of manufacture, an annular domestic heater, adapted tobe applied to and removed from the exterior of a stove-pipe, or theexterior ot' the drum of a stove, such hea-ter being constructed ot'annular plates b, b2, connected together by plates d c, the plate dbeing provided with apertures d1 d3, cap or cover d?, and pipe di, andthe external plat-c b1 having applied thereto a gage, j', and .tap g,all arranged and construct-ed substantially as shown and described.
